The KIDFIX SL is a highback booster seat with flexible installation options to suit any vehicle – from the innovative soft-latch connectors to the car's 3-point seat belt. Enabling easy transfer and installation of the seat to meet the needs of the busiest lifestyle.
Good to know: The KIDFIX SL has been tested by ADAC (ADAC Motorwelt 11/2015) with a rating of “GOOD” and a grade of 1.8.
Large side wings for comfort and safety
Offering an additional level of protection, KIDFIX SL is a highback booster seat with deep, softly padded side wings that are designed to give the comfort and safety that older children need when they are travelling. It provides head-to-hip protection for your child and ensures that every journey is safe.
Easy installation and comfort
Quickly and simply installed using the car’s ISOFIX anchorage points, KIDFIX SL is permanently attached to the vehicle even when there’s no child in the seat. And thanks to its soft-latch connectors that attach individually, finding and securing the anchorage points is easier. The seat belt guides automatically adjust as you change the height of the headrest so that the seat belt is always correctly positioned to provide the correct fit for your child. As your child grows and their shoulders get wider, the V-shaped backrest ensures a comfortable fit throughout.
Designed to give optimum support to your growing child, the V-shaped backrest provides more space for their back and shoulders. Plus, the adjustable backrest allows you to match the angle of the vehicle seat, providing a better fit and a comfortable position for your child.
Our highback boosters protect your child in 3 ways: the seat shell provides head to hip protection for your child, especially in the event of a side impact; the upper and lower belt guides provide correct positioning of the seat belt; and the padded headrest provides safety and comfort for your child’s head and neck.
Our headrest is designed especially for older children, when using the 3-point seat belt to secure them in the car seat. It can easily be adjusted to the correct position, just above your child’s shoulders, with one hand – even while they are sitting in the seat. Plus the headrest is ergonomically designed to support your child’s head when they fall asleep.
